Looking through the ski race results, a couple of intersting things... looks like there was a 28 Pantera running (actually looks like they won their class) and a dude named Carly Sanchez also in the race in an F_______ who, I think, is Jo's cousin and owner of a nice six man race boat.
2 different boats. The one on the video is owned by Rick Karr and is a Sport model while the other in the Catalina Ski race pics. is a 24 SE. Both of them are located in CA.
My Mother's cuzin Carly Sanchez does have a 6 man bolster 28' Single in Torrance, CA.
